Aortic valve sparing techniques in aortic root dilatation

The development of the Bentall-Bono technique in the 1960s allowed the prophylactic treatment of the aortic root aneurysms, increasing the survival of these patients. Valve sparing techniques were developed later, in a response to the potential complications related to mechanical prosthesis and long-term anticoagulation associated to the Bentall-Bono procedure. The results of these techniques in the hands of experienced teams are excellent, and they have become an important tool in the therapeutic arsenal of the cardiovascular surgeon in this pathology. In order to achieve the best surgical results, these techniques should be performed in experienced centres. (c) 2022 Sociedad Espanola de Cirugia Cardiovascular y Endovascular.
